Notebooks in Azure Databricks

Azure Databricks Notebooks support four programming languages, Python, Scala, SQL and R. However, selecting a language in this drop-down doesn’t limit us to only using that language. Instead, it makes the default language of the notebook. Every code block in the notebook is run independently and we can manually specify the language for each code block.

Before we get to the actually coding, we need to attach our new notebook to an existing cluster. As we said, Notebooks are nothing more than an interface for interactive code. The processing is all done on the underlying cluster.

Read on to learn how Databricks uses the notebook metaphor heavily in how you interact with it.
